We live in a neighborhood and had two precious roos. When they began crowing, we brought them into our utility room every morning (about 4:30 AM). They had a roost, feed, water, and about 80 sq. ft. to roam about. They would hop atop their roost and crow until about 7:00 AM each morning. (We loved hearing them and it kept the neighbors from being disturbed.) We finally rehomed to a lovely farm where they could crow all day (as after reaching about 6 months of age, they began doing just that - crowing at random times of the day). We were quite fond of our roos, but also wished them to have a good, natural life. I suppose it depends upon your roo. If he only crows in the morning, you might bring him indoors for a bit until he stops. If he crows throughout the day, it would be best to find him a new home (or, if you prefer, humanely cull and utilize him for a meal). I would NOT recommend any type of caging that restricts movement or "decrowing", personally....
